This invention relates to the field of cable technology, specifically to a high-performance polyvinyl chloride (PVC) cable material and its preparation method. The cable material is based on PVC resin, combined with plasticizers and multifunctional flame-retardant composite fillers, with the filler content being 85-95 parts by weight per 100 parts by weight of resin. The multifunctional flame-retardant composite filler employs a multi-layered interface design: using magnesium hydroxide / calcium carbonate as the core, it first undergoes silane treatment to introduce epoxy sites, then constructs a phytic acid-tin-calcium-zinc chelate layer, and immobilizes double-grafted modified carboxymethyl-β-cyclodextrin, ultimately forming a tannic acid-metal ion polyphenol network layer. The preparation method includes pre-plasticization, segmented mixing with filler addition, and extrusion granulation. This invention effectively improves the filler-matrix interface compatibility, enhances flame retardancy, mechanical properties, and thermal stability, and solves the problem of insufficient durability in high-filler systems.

The application provides a low-temperature high-conductivity polyether electrolyte and a preparation method thereof. The polyether crosslinking network is formed by crosslinking polyethylene glycol monomethyl ether methacrylate and polyethylene glycol diacrylate, tri(pentafluorophenyl)borane and lithium salt are introduced to form a borane-lithium salt complex system, the molar ratio of lithium ions to borane is accurately controlled to be 1:0.02-0.20, and the acetonitrile complexing-vacuum desolventizing-in-situ polymerization curing process is used, so that the high-purity thin film electrolyte with the ion conductivity ≥1*10 ‑4 S / cm, residual acetonitrile ≤500 ppm and moisture ≤1000 ppm at low temperature is realized, technical problems that the low-temperature conduction capacity decreases when the crosslinking modulus of the traditional polyether electrolyte is improved, the processing window of the high-lithium salt system is narrow, and the interface stability of residual solvent and moisture is difficult to consider are effectively solved, and the low-temperature performance, processing stability and wide solid-state lithium battery application prospect are excellent.
